I can teach you, but I'm still willing to tell you where the information is. China Com has delicious food and a gourmet blog. There are too many, Baidu can find them. Tell you the simplest one, buy a piece of tofu, buy onions, cut chopped green onion, put chopped green onion on the tofu, put proper amount of salt, put proper amount of monosodium glutamate, put oil, which can be soybean oil or Chili oil, and stir. Very delicious.
